v AIRORAFT WING.

Application led March 1924.. Serial No. 701,734.

H1 of the areas.

Another object is to provide a means of enlarging or decreasing both the longitudinal and transverse dimensions of the wing.

To maintain aliforniity of the wing sur- I5 faces and to provide a means of varying the Z0 correspondingly slowtakeotfs can be made,

all of which increase the factors of] safety of operation in proportion to the speed and momentum involved in all ground speeds,

while in flight, as the forward velocity is in- 2,5 Vcreased the wing surfaces may be commensurately decreased so as to secure a constant lifting effect proportioned only by the load in all altitudes. By so constructing the Wing as shown in my device less power will be required from the engine for propulsion at high velocity and inversely and concomi- -tantly high speeds may be attained economically, with less skin friction due to less areas exposed, all of which increases the desirability of aircraft for military, civil and commercial purposes since time will be reduced economically between given' points of travel and, also, since less engine power is required less expense will be occasioned by the operation thereof, as well as less costwill be involved in the construction and operation of the engine, as can be readily understood. To supply this want the present evolvement is made.

Having thus disclosed the principal objects of the present invention, and while other objects may be apparent from the reading of this specification and of the claims, I will now describe the invention 5U with reference to the accompanying drawings which forman essential part, though an illustration of, the invention as disclosed in this specification.

Figure 1 is a plan view, of the wing with the internal mechanism, relating to the means of longitudinal variations, shown in dotted lines. v

Figure 2 is the) same View with the interl nal mechanism, relating to the means of transverse variations, shown in dotted lines.

Figure 2?Y is a cross-sectional view of th(` wing taken on line 3-3 shown in Figure 2, looking in the direction indicated by the arrows.

Figure 4 is an enlarged perspective des tailed view of the sliding brace memberan ranged atthe forward or outer ends of the i Figure 5 is a plan view of the aircraft showing in dotted lines the areas of the wing surfaces when increased. y

Figure 6 is an enlarged perspective detailed view of the shaft and-sleeve ofthe mechanism relatingto the outward .transverse lazy tongs shown in `Figure 2.

In carrying out my invention, wing base 1, is attached to body 2 ofthe aircraft as illustrated in FiguresA 1,2 and 5. Within wing base 1 a longitudinalsupporting sleeve member 3 is arrangedas shown by dotted lines in Figure 1, within which tubelfl:v is slidably arranged to support the sliding wing base 5 -as shown in Figures 1` and 2. Telescoping wing base 6 isk arranged over wing base l as shown in Figures 1,' 2, 3 and 5, while in sliding Wing base 5 thetelescoping sliding wing portion 7, shown in Figures l, 2 and 5 is arranged. The said ltelescoping wing` base '6' is'carried by supporting sleevemember 8, shown in Figure 1, while the telescoping portion of sliding wing 7 is held upon tube 9, also shown in Figure 1. Longitudinal lazy tongs 10, shown in Figure l, is attached to supporting members 11 and 12, the said members being threaded to engage right-hand and left-hand threads on shaft 13 carried on journals 14. and 15, as shown in Figure 1, while the outward end of the said lazy tongs is attached to the telescopin portion of sliding wing 7 lby means of racket and. pivot 16, while the opposite and forward memberof the laz tongs is attached to bracket and pivot 1 held upon the telescoping portion 7, shown in Figure 1 as detailed, and shown in enlarged view in Figure 4.

Sliding wing base 6 and telescoping portion 7 are supported transversely by sleeves 18 and 19 respectively, arranged in wing base l and sliding wing base 5, as illustrated in Figure 2, within which rods 20 and 21 respectively, arranged upon 4telescoping base 6 and sliding wing portion 7 as shown in Figure 2, While the transverse lazy ton s 22 and 23 are held in their respective t readed members 24 and 25, and 26 and 27, respectively, as can be readily seen and substantially as described with refer` ence to the longitudinal lazy tongs 10 with reference to sliding bracket 17, as illustrated in Figure 4.

Supports 24, 25, 26 and 27 are arranged upon opposed threaded ortions of shafts 28 and 29 held by journa s 30, 31, 32, 33, 34 and35, all shown in Figure 2 and in part in Figure l.

Shaft 13 is rotated by bevel gear` 36 attached thereto engaging bevel gear 37 attached to shaft 28, While gear 38 on shaft 13 engages gear 39 'on shaft 40, as shown in Figure' 2. Shaft 40 is Slidably arranged in shaft 29, asshown in Figure 2. and as shown in enlarged detailed view in Figure (i Control Wheel 41 is attached to shaft 28 and supported therewith by journal 42, as shown in Figures 1 and 2.

Thus it will be seen'tliat by turning control wheel 41 revolving shaft 28 in journals 42, 30, 31 and 35, the said shaft 28 carrying right-hand and left-hand threaded portions engaving supportingmembers 24 and 25 of the lazy tongs 22, that the said sup porting members 24 and 25 will be moved towards or from each other as Wheel 41 is iotated 'right-handedly or left-handedly, as can be readily understood. It will be further seen that simultaneously with the rotation of shaft 28` through-gears 37 and 36, shaft 13 will be rotated and through gears 38 and 39, shaft 40 .arranged Within sliding shaft 29 will move lazy tongs 10 in a longitudinal direction and lazy tongs 23 in a transverse direction, respectively, as can be readily` understood. Thus the wing areas ma be enlarged or diminished simultaneous y as indicated by arrows 44 and 45, as shown in Figures 1, 2 and 5.

Of course it will be understood that vari' ous changes may be made in the adaptation, association, arrangements and collocations of parts as well as in their means of control without departing from the spirit of this invention.

scoping wings.

I-Iavinff thus described my invention in its preferred form, as shown and illustrated, what I-claim and for which I desire to se cure Letters Patent are as follows:

1. In an aircraft Wing, thc combination of: a fixed wing section; a sliding wing section; a teleseoping wing section arranged over the said fixed wing section; a telescoping wing section arranged over the said sliding wing section; a manually operated mechanism mounted within the fixed wing section and in the sliding Wing section, forining means of simultaneously enlarging the wing surfaces.

2. In an aircraft wing, the combination of: a fixed wing base; a sliding wing, a telescoping wing arranged over the said fixed.

wing base and over the sliding wing portion and a lazy tongs operatively mounted withinv the said fixed Win and manually controlled for moving the siding and tele- 3. In an aircraft wing, the combination of a base member, a telescoping member operatively mounted over the said base inember, a sliding wing member operatively mounted within the said base member, a telescoping member operatively mounted over tlie sliding member, and means arranged within the said base member and the said sliding member and operatively associated with the said telescopic members for moving the telescoping members transversely and for simultaneously moving the sliding member longitudinally of tliesaid wing.

4. In an aircraft wing, the combination of a base, a sliding portion arranged within the said base and movable arallel to the longitudinal center of the said base, a telescoping portion 'forwardly disposed and movable transversely of the longitudinal center of the said base, a telescoping poi tion arranged over the sliding portion, the said telescoping portion being movable transversely of the longitudinal center of the saifd base and a manually controlled mechanis'in arranged to actuate simultaneously the Vt'e'lescoping and sliding portions of the said Wing. y

In testimony whereof I have signed this specification.
